Ds1 and dd are ecstatic - neither of them 'believe' in FC (we just have never 'done' that, but they like the story) - they are 6 and 4 - but we just heard carols, opened the door, and coming down our road was an excellent lit up sleigh, with lit up reindeer, and a fab Father Christmas on the sleigh (on the back of a car iyswim) - they were so excited, gave some money for the charity, got lollies, and ds1 shouted HO HO HO - and FC bowed very low to him.
Proof that you don't need to 'believe' for it to be utterly magical!
